Abstract

In order to place a protective muff 14 of plastic around a joint between pre-manufactured, heat-insulated pipes, preferably subsurface district heating pipes, an axially slitted muff tube 16 of plastic is inserted sideways over the joint such that a bridge between the facing ends of the outer jacket tubes 10 of the joined pipes, said jacket tubes also being made from plastic. A plastic welding strip 20 provided with a number of embedded, parallel heating wires 34 is placed alongside and over the respective butt seam 46 with its opposing ends situated at some distance from each other on each their side of the axial tube slit 18. The ends of the strip 20 are provided with terminal parts 22 for connecting in parallel of the embedded wires, and these are heated electrically for welding together of the welding strip and the two plastic pipe ends. Subsequently, the axial slit 18 is closed by means of a corresponding welding strip 54. Hereby, an extremely good and tight joint is ensured, which can be made in simple way by non-highly qualified fitters. A welding element according to the invention is constituted by said welding strip 20, 54 either by itself or in combination with a muff tube 16. <IMAGE>
